How can I resolve the error "Different type of tendon material exists within the Tendon Group" that occurs when performing PSC design in my model?
As you see below, different tendon properties are used in the same tendon group. This is not allowed for the PSC Design. These two tendon profiles are assigned to two different girder and, thus, these two tendons should not be assigned to the same tendon group. You need to make it different tendon groups.
